TO lALL' WHOM IT MAY' OONCERN:

Be it known that I, ALMON-D. MANLEY, of Washington, in the county ofMacomb, and in the State of Michigam have invented a new and usefulImprovementriu Hoisting and Transferring-Pulleys; and do hereby declarethat the following is a lfull, clear, and exact description thereof,reference being had to the aecompanying drawings, and the letters ofreference'markcd thereon.

In the annexed drawings, making a part ofhthis specification, Arepresents a suitable frame, composed of a horizontal beam, supportedupon legs therefor, and B represents a peculiar-shaped head-block, madesubstantially in the form shown in the drawings. The head-block B issuspended beneath the beam ofthe frame'A by means of slots in thenpperside thereof working on and catching over headed bolts orserews'whieh project downward from the frame A. .j I A A winding-drum,K, is adjusted in the head-block B, for the' purpose of tightening'arope, C, which I call e the track-rope, and a pulley, It, in 'the lowerpart ofthe l1eadblock, below' the rope C, over which a draughtrope orcord, F, passes. Y

The head-block is made double, or so as to receive the pulley-block Dbetween the sides, and is provided with projections orrests, on whichthe inclined ways t work when the pulley-block D is drawn up into it.The head-block is further provided with notches or catches on` theinside, and nearthe bottom of its sides, in which the end or catch onthe end of the small leverj is caught, when the pulley-block D is drawnup into the head block B.

K represents a winding-drum, adjusted loosely on its shaft, so that itwill slip laterally thereon, so as to keep the rope always in a linewith the middle of the head-block when winding up the sanne. Said drumis provided with ratchet-teeth, on a i'lange at one end thereof, as' isfully shown, by which means it is operated and held in place.

The winding-drum K is turned, and the track-rope thereby tightened, bymeans of a lever, L, made for the y purpose. Said lever L is providedwith two lips or projections from one side and end.thereof, as is shownin Figure 3, one of which catches inside the rim of the wheel or drum,and the other in the teeth thereof, and thereby locks with and turns thesame. i f

The winding-drum K is provided with a notch or bite, b,`in which a ropemay be readily secured at any time without tying the same. C l v y Thetrack-rope C is secured, at one end, in the frame A, and extends acrossto the head-block B, and'through between the arms which support thepulley and to theV winding-drum K, where it is caught in the notch b.and then tightened by means of the lever L and drum B. l Y

D represents a pulley-block vor car, which is suspended and works uponthe track-rope C, and is operated or moved forward by means of'powerattached to the draught-rope F. The ear or pulley-block D is made'in twoparts, and hinged together'justabelow the track-rope C. The upper partof lthe pulley-block D is provided with ways, it, on each side, which'tand work up in the head-block. B, on suitable rests therefor.

N represents a small lever or catch, which-is pivoted in one end of thelower part of the pulley-bloek, the end of which is made concave, so asto lit over a rope, E, as is shown. Said levei is also provided with aprojection or tongue, which ts in the groove, c, of the sliding bar g. l

E represents a rope,towhich is attached the weight w, at one end, andpasses thence up over the pulley P, and out to the end ofthe frame A,and there secured. The rope Eis made of any length desired, andregulated, as may be required for length, over a pulley in a slot in theend of the frame A. i

A. small collar, sv, is fastened to the rope E, near where the weight isattached,-whiehiis caght by the lever N, and the-weight is thereby heldup when once elevated.

g represents a movable bar, made in the form shown, providedl withshoulder or catch z', groove or notch e,

and bevell'ed projection e.

By attaching power to the draught-rope F, and. drawing the carerpulley-block D forward, it will be seen v that the weight will beelevated, and, as the ropeE is taken up, the collar :v will pass up andagainst the catch or shoulder z', when the lever N is drawn over, bymeans of its tongue working in the groove c, and, at the same i time,the bevelled projection z throws up the end of the lever j, and its jaws'or catches down, so that, as theyr pass into the head-block B, theycatch in the recesses or notches therefor. l

H represents an adjustable collar, for the purpose of .stoppingandrholding the car or pnlley-block D from running too far hack whenloosened from the head-bloeli B. Said collar His made with a smallplate, m, which is pressed firmly against the rope by means of thedouhleelhow-lever l, as shown in the drawings.

The lever Z, and thereby the collar H, may he moved or operated by meansof a hand-cord, I.

When the pulley-block D runsout, and strikes against the lever l of thecollar H, the sliding harig is thrown or pressed. back, and thereby thelever N is detached from the collar rv, and the weight then falls downwithout obstruction. p

i Having thus fully described my invention, what'I claim as new, anddesire to secure by Letters Patent, is-

The arrangement of the block B, drum K, pulley It, and lever L, incombination with the car D, and its pulleys, levers N and j, sliding harg, pulley P, and cords E C F, adjustable collar H, and weight w, thevarious parte being c onstruotelland operating substantially as setforth.

'Intestimony that I claim the foregoing, I have hereunto set my hand.and seal, this 28th day of January, 1868.
